Democrats picked up a Republican Senate seat in the Hoosier State, while Senate Democrats in Michigan, Minnesota and Ohio all won re-election. The party also held onto the seat vacated by retiring Wisconsin Sen. Herb Kohl.

Democrats also picked up House seats in Illinois and Minnesota — losing only one in Indiana — and maintained the status quo elsewhere in the region.

Things went particularly well for Democrats in Obama’s home state of Illinois.

An open-seat race in the 12th district that Roll Call rated as a Tossup went to Democrat William Enyart, and the 13th district went to Republican Rodney Davis.

Democratic Rep. Jesse Jackson Jr., who has been absent from Congress and the campaign trail since June, coasted to victory in his Chicago-area district despite being treated for bipolar disorder at Minnesota’s Mayo Clinic.

Democrats lost a House seat in Indiana,&nbsp; but only because its former occupant lodged a successful Senate bid.

Rep. Joe Donnelly (D) defeated state Treasurer Richard Mourdock (R) in a Senate race that Democrats spent money on early and often.

The contest was in large part competitive because the tea-party-backed Mourdock ousted popular six-term Sen. Dick Lugar in the GOP primary. It became even more so after Mourdock said in his last debate with Donnelly that he believed pregnancy resulting from rape was something “God intended.”
